Nonprobability sampling

The focus of my field research was to attempt to discover people’s opinions of the NSA mass data collection programs. There are various surveys showing opinions on the Internet, but none specifically focusing on the area where I lived. So, I decided to create my own survey. Based on the general topic, I decided that most people would have a negative opinion, as America was founded on principles of freedom from government intrusion. As for my choice of a survey, I decided on it because a survey…

Of the studies identified as measuring speech perception or speech recognition, 10 were non-randomized treatment studies and 3 were randomized controlled trials. Due to their quasi-randomized study designs, De Miranda et al. 2008 and Stecker et al. 2006 were considered as non-randomized treatment studies. Of the thirteen studies, 3 were conducted in Portuguese Brazilian in Brazil. The rest were conducted in English in the United States. All articles were published in English between 1987 and…

According to Bachman & Schutt (2014): Research should expose participants to no more than minimal risk of personal harm, researchers should fully disclose the purposes of their research, participation in research should be voluntary, and therefore subjects must give their informed consent to participate in the research, and confidentiality must be maintained for individual research participants unless it is voluntarily and explicitly waived. (p. 60) Although Dr. Coswalt protects the research…

Another type of sampling is systematic random sampling (Chamberlain, 2016). Using this method, researchers should develop a comprehensive list that is not structured (Chamberlain, 2016). Once the list has been compiled, the researcher should choose a random spot on that list, based off of the total sample size, and then select by interval moving forward (Chamberlain, 2016). While drawing a random sample is ideal, it is not always feasible. Therefore, another alternative sampling approach,…

Studies and information gathered from the population offers a valuable tool for a marketing manager to utilize when one is trying to increase wine sales in an operating establishment. Many studies exist, which concern factors shown to influence dining satisfaction such as the quality of food, the quality of the service, as well as the environment and ambiance. However, nominal research exists, which focuses on the customer’s satisfaction with wine when they are in a restaurant atmosphere, while…

At the same time, during the sampling of this study, the sample may not be evenly distributed to the first, second and third tier cities in China, which could have a certain impact on the results of the study. For example, recreation facilities construction in China 's third-tier cities…

Yes/No); nominal (gender, race); ordinal (age group) and quantitative-discrete (number of medication errors) or continuous (amount of time-time to balloon, ED waiting time). Measure phase might make a use sampling for data collection (simple random sampling, cluster sampling, stratified sampling). Sigma Six uses following formula to decide on the sample size (n) for continuous data: n= (1.96ϭ/∆) ^2, and n= (1.96ϭ/∆) ^2*P (1-P) for discrete data. Where P is the estimated percentage of the…

Notably, random sampling method was applied in the research. This ensures that error that result from bias are zero rated in the research. Moreover, random sampling is easy to apply as well as accurate in cases of large population under study, as was the case with music therapy. Overall, the selected sample represents 17 percent of entire…
